Abstract:
A pointer speed adjusting method is used in a display system including a pen-shaped pointing device and a display screen. The pointer speed adjusting method includes the following steps. Firstly, a moving trajectory of the pen-shaped pointing device is sensed. Then, a trajectory display pattern is obtained according to the moving trajectory. Then, the trajectory display pattern is compared with a reference display pattern shown on the display screen, so that an optical scale factor error is obtained. Afterwards, a speed conversion ratio is adjusted according to the optical scale factor error.
Abstract:
The present invention is to provide a network system for transmitting various signals and power, which comprises at least a power sourcing equipment and at least a powered device over a network. Each of the power sourcing equipment and the powered device has at least a port, wherein a first isolated conductor is disposed at one side of the port while a second isolated conductor is disposed at the other side of the port and creates a power circuit for transmitting power in combination with the first isolated conductor. Four differential signal pairs of the port, each with two conductors, are disposed between the first isolated conductor and the second isolated conductor, wherein each of the power sourcing equipment and the powered device transmits Ethernet signals through two of the differential signal pairs of its port and transmits other network signals through the other two differential signal pairs.
Abstract:
A scroll saw blade holding system comprises at least an upper scroll saw arm with a notched, forked end, a pair of plate members held together by a screw for clamping an end of a scroll saw blade, and a pivot pin, extending through the plate members and shaped to rest within the notch in the scroll saw arm. The pin preferably includes a longitudinally-extending, knife edge pivot point which allows the plate members and blade to pivot relative to the scroll saw arm. Also in a preferred embodiment, a blade retaining assembly is included and comprises a bracket attached to the saw arm and a lock knob and bolt positioned above the plate members for retaining the pin within the notch.
Abstract:
An optical critical dimension measuring method, applicable in measuring a pattern, that includes a plurality of polysilicon layers, of a device, is provided. The method includes obtaining a real curve corresponding to the to-be-measured device. Then, determining whether an ion implantation process has been performed on the polysilicon layers, a different module is selected. A correlation process is performed according to the selected module to generate a theoretical curve that correlates with the real curve to obtain a plurality of parameters corresponding to the theoretical curve.
Abstract:
A connector structure of assembled house truss is disclosed. The respective support members of the house truss are inserted and fixed in the connector by screws so that the support members can be quickly and easily assembled by a general person to form the house truss without welding operation and using any power.
Abstract:
An image auxiliary data searching and displaying method is used in a document camera. The document camera includes a processor and a user interface. The processor is accessible to a database. The image auxiliary data searching and displaying method includes steps of performing an image-selecting operation on an image of the to-be-displayed object via the user interface to generate a target image, processing the target image by the processor to generate a target characteristic property, searching the database by the processor according to the target characteristic property so as to generate a search result, and simultaneously displaying at least one image auxiliary data from the search result and the image of the to-be-displayed object for comparison.
